Andreas Feininger--one of the foremost photojournalists of the 20th-century and a long-time photographer for Life magazine--has divided the book into two parts: Technique and Art. The first presents information about equipment, materials, darkroom, camera and processing negatives and prints; the second section--The Art of Making a Photograph--goes into contrasts, color, space and perspective, lights and lighting, motion, composition and the picture story. For years, one of the key how-to photography books.
